During an attempt to connect to the PostgreSQL running on this host – the “FATAL: Peer authentication failed for user “name”” appears. And the same error… Read More: PostgreSQL: FATAL: Peer authentication failed for user “name”0 (0) »

Bitwarden: an organization’s password manager self-hosted version installation on an AWS EC2
0 (0)

1 May 2019

We consider Bitwarden as a passwords keeper for our project with the main goal to have an ability to have separated access to secrets by user roles and/or ACLs. I.e. Pass or KeePass are good for self-usage by one person but they have no main things – a normal web-interface and role-based access to data.… Read More: Bitwarden: an organization’s password manager self-hosted version installation on an… »

The most known implementation is Google Authenticator but also there is a lot… Read More: Authy: step by step Multi-Factor Authentication configuration for Github and… »

16 April 2019

Proceeding with a Github repositories checker. To recall: the idea is to have such a check in case if somebody from developers accidentally will share our project’s private repository as public, or will create a public repository instead of making it as a private one – we will get a Slack alarm about such a… Read More: Jenkins: a job to check a Github organization’s public repositories… »

The original post (Rus) was written almost right after the well-known Not a Petya attack in Ukraine – that’s why it’s used in the title. I had a new project assigned to me. When I started its existing setup investigation – was just shocked.… Read More: MySQL/MariaDB: like Petya ransomware for MySQL and ‘root’@’%’ access0 (0) »
